Sinopec News Network reported on August 6 that the new quench water system transformation project of the joint MTO unit of Zhongan Group was successfully commissioned and commissioned
.
At 9:30 a.
m.
, at the MTO plant site, the operator opened the feed valve on time, and the new quench water system transformation project began to commission the trial run
.
After half an hour of stable operation, comparative analysis of import and export sampling materials, the filtration effect of the quench water system is obvious, and it meets the design requirements, indicating that the project has been successfully commissioned
The quench water system transformation project is a technical transformation project for the MTO device to solve the bottleneck problem of long-period stable operation and economic operation of the MTO device.
It is composed of 6 fluidized bed filters in parallel.
The main function is to filter the quench water to ensure the stable operation of the device
.
The project was completed on July 1st, and the project was ready for commissioning after the on-site "three inspections and four determinations", problem rectification, and confirmation of commissioning conditions
Since Zhongan United Coal Chemical's production was transferred to commercial operation, the MTO unit has been operating at a high load, providing sufficient raw materials for the stable and high output of downstream devices, which is a strong guarantee for Zhongan United to achieve the goal of increasing production and efficiency
.
With the continuous extension of the operating time of the MTO device, the problem of excessively high catalyst solid particle content in the quench water circulation system has gradually emerged.
The quenched water boiling bed filtration technology adopted this time has the characteristics of high separation efficiency, low energy consumption, high wastewater reuse rate, small equipment investment, low operation and maintenance costs, etc.
